Double major for foreign students

I’m in the 11 grade and my GPA is an A+ so i think it’s acceptable, even though, i stills need some other skills and competences , for me : I speak 4 languages(arabic, french, english and spanish)
My GPA is an A+ which is good i guess
but i think i might need some other competences like i got to train for and SAT or ACT and get an TOFL, you can tell me some other things that i got to prepare ? Thank you again.
